Cannot find symbol for selection sort algorithm

[iceyferrara]

My problem is that my compiler tells me it cannot find my selectionSort method when i call it. Can some one help?

heres my code, in two classes, cuz thats how its gotta be done.

import java.util.*;
import java.io.*;
public class NumberArray
{
	public static void main(String[] args) throws IOException
	{
		Scanner keyboard = new Scanner(System.in);			//Create Scanner object so user can input the file name
		System.out.println("Please enter the name of the file with the numbers you were given:");
		String givenNumbers = keyboard.nextLine(); 			//Store the filename to a string varaible

		File file = new File("givenNumbers");				// Use the variable to open a new file
		Scanner inputFile = new Scanner(file);				// Scanner inputFile allows the numbers in the file to be read

		int index = 0;
		double[] fileNumbers;								//Set index to 0 and create a double array to store numbers for sort

		while (inputFile.hasNext())
		{
			fileNumbers[index] = inputFile.nextDouble();	//Since each number is on a new line in the file, this will store the numbers into the array
			index++;
		}

		selectionSort(fileNumbers);

		inputFile.close();									//Close the file
	}
}

import java.util.*;
public class NumberAnalysis
{
    public static void selectionSort(double[] numbers)
    {
        int scan, index, minIndex, maxIndex;
        double maxValue, minValue, average, total;  // Declare variables to store max and min values
        total = 0.0;                                // and their indexs, along with scan, average and total
        maxValue = 0.0;                             // Initialize these variables before loop so can be called after
        minValue = 0.0;

        for(scan = 0; scan < (numbers.length-1); scan++)
        {
            minIndex = scan;
            minValue = numbers[scan];                   //Scan represents first index of array, 0

            for(index = scan + 1; index < numbers.length; index++)
            {
                if (numbers[index] < minValue)
                {
                    minValue = numbers[index];          //This if statement sorts the array throughout the whole
                    minIndex = index;                   //for loop. From lowest to higest numbers
                }

            }
            numbers[minIndex] = numbers[scan];
            numbers[scan] = minValue;
            total = total + numbers[scan];
        }
        maxIndex = numbers.length - 1;                  //Selection sort makes the last index in the array the highest number so assign that to maxIndex
        maxValue = numbers[maxIndex];                   //maxValue is equal to the last number in the array so call it using maxIndex
        average = (total / numbers.length);

        System.out.println("The lowest number in the array is: " + minValue +
                            "\nThe highest number in the array is: " + maxValue +
                            "\nThe total of all the numbers in the array is: " + total +
                            "\nThe average of all the numbers in the array is : " + average);
    }
}

The first set of code is the one with the error, the second set of code compiles correctly. I appreciate any help or insight on my problem. Thank you

Which class does the selectionSort method reside in?
